Abstract
THE modern version of the Hubble diagram in which the log of the redshift is plotted against apparent magnitude corrected for redshift and absorption effects of clusters of galaxies, is in principle capable of yielding several cosmologically useful pieces of information. In this letter I report evidence for a significant and substantial departure from the expected redshift for the Virgo cluster of galaxies. A peculiar velocity of 658 ± 96 km s−1 is derived but because of Virgo's membership in the Local Supercluster, such a value is not unexpected. Thus the turbulence recently observed by Smoot et al.1 for the Galaxy's motion within the Hubble expansion is present elsewhere in the Universe as well. Because the Virgo cluster does not exactly follow the Hubble law, a new value for the Hubble constant equal to 43.4 ± 2.6 km s−1 Mpc−1 is found leading to an observable Universe 1/4 to 1/3 again as large as was previously recognised.
